【Abstract】 In order to improve the ability of real-time processing and data management efficiency of simulation software used in aerospace camera testing work, an effective simulation software of 1553 B bus was designed by using VC + + to meet the need of testing task of a certain aerospace camera. Multi-thread technology and database access technology were used in the software. It can work as the satellite platform to provide parameters and instructions for the aerospace in orbit, and monitor the working state of aerospace camera. In addition, it provides good man-machine interface and database support. Software architecture and implementation method were described, a new synchronization message processing mechanism and management methods were put forward, which improve the ability of real-time processing ability of the software. Test result shows that the software is stable and has good effectiveness. It can satisfy the requirements of ground-test of aerospace camera and possesses practical application value in projects.更多还原
